Description

Technical Field

[0001] This utility model relates to the technical field of automatic corrugated cardboard bonding machines, specifically an automatic corrugated cardboard bonding machine. Background Technology

[0002] Corrugated cardboard, as a core material in the modern packaging industry, is widely used in logistics and transportation, electronic products, food and pharmaceuticals, and other fields. Its multi-layered structure (usually composed of face paper, corrugated core paper, and liner paper) is bonded together with adhesives. It needs to meet comprehensive performance requirements such as high strength, moisture resistance, and lightweight. Sometimes, multiple sheets of corrugated cardboard need to be bonded together to improve the impact resistance of the cardboard.

[0003] In the existing corrugated cardboard bonding process, the equipment applies glue and then the cardboard is manually removed and glued. Manual alignment relies on visual judgment, which makes it difficult to ensure that the edges of multiple layers of cardboard are completely overlapped. This results in a lot of waste during the subsequent cutting process. Therefore, we have proposed an automatic corrugated cardboard bonding machine to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic corrugated cardboard gluing machine to solve the problem mentioned in the background art of excessive waste generated during the cutting process after manual alignment and gluing when using the automatic corrugated cardboard gluing machine.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an automatic corrugated cardboard bonding machine, comprising a base plate and a frame;

[0006] The base plate is provided with a frame at the top, and a feeding belt is provided inside the frame. A drive chamber is provided at the top right side of the frame, and a moving block is slidably provided on the drive chamber. The drive chamber is connected to the moving block through a moving component. A glue dispensing head is installed on the left side wall of the moving block. A pressing component is provided on the top left side of the frame, and a fixing plate is provided inside the left side of the frame.

[0007] A storage box is provided on the top front side of the base plate. Threaded rods are threadedly connected to the middle of the two side walls of the storage box. A push plate is rotatably connected to the front end of the threaded rod. A fixed column is provided on the top of the base plate. A rotating rod is rotatably provided on the top of the fixed column. A rotating plate is provided on the top of the rotating rod. Mounting frames are provided below both ends of the rotating plate. Multiple sets of suction cups are provided at the bottom of the mounting frames. A first cylinder is provided at the top of both ends of the rotating plate. The output end of the first cylinder is connected to the center position of the top of the mounting frame.

[0008] A further improvement is that two sets of limiting rods are slidably provided on both sides of the storage box, and the front ends of the limiting rods are respectively connected to the side wall of the push plate on the same side. The push plate is L-shaped, and the bottom of the push plate is slidably connected to the inside of the storage box.

[0009] A further improvement is that sliders are slidably provided inside both sides of the frame, and the top of each slider is connected to the bottom of the drive compartment on the same side.

[0010] A further improvement is made in that: a lead screw is rotatably provided inside the front side of the frame, and the lead screw is threadedly connected to the internal slider on the same side; a slide rod is provided inside the rear side of the frame, and the slide rod is slidably connected to the slider on the same side.

[0011] A further improvement is that the moving component includes a rotating shaft, a gear, and a rack. The rotating shaft is rotatably mounted inside the moving block. Moving grooves for the rotating shaft are provided on the upper and lower side walls of the drive compartment. A gear is mounted on the rotating shaft. A rack that meshes with the gear is mounted on the inner side walls of the drive compartment.

[0012] A further improvement is that the pressing assembly includes a mounting plate, a connecting plate, a second cylinder, and a pressure plate. The top of the frame is provided with two sets of mounting plates, which are connected by two sets of connecting plates. The top of each set of connecting plates is provided with a second cylinder, and the output end of the second cylinder slides through the connecting plate and is connected to the pressure plate.

[0013] A further improvement is that: both sets of mounting plates have sliding rods that pass through them on both sides, and the lower ends of the sliding rods are connected to the top of the pressure plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this automatic corrugated cardboard bonding machine, after placing multiple cardboard sheets into the storage bin, rotating the threaded rods on both sides drives the push plate to move towards the center simultaneously. After the push plate aligns the cardboard, the first cylinder drives the mounting frame to descend, and after being adsorbed by multiple sets of suction cups, it rises. The rotating rod drives the rotating plate to rotate 180 degrees, placing the cardboard above the feeding belt. At the same time, the mounting frame on the other side adsorbs new cardboard, and the moving mechanism, in conjunction with the lead screw, drives the glue applicator to move, applying glue to the surface of the cardboard. After the new cardboard is placed on top, the pressing mechanism presses it to complete the rapid bonding of the cardboard.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an automatic corrugated cardboard bonding machine, comprising a base plate 1 and a frame 2;

[0022] A frame 2 is mounted on the top of the base plate 1. A feeding belt 3 is installed inside the frame 2. Sliding sliders 26 are slidably mounted inside both side walls of the frame 2. The tops of the sliding sliders 26 are connected to the bottom of the drive chamber 4 on the same side. A lead screw 24 is rotatably mounted inside the front side of the frame 2, and the lead screw 24 is threadedly connected to the sliding slider 26 on the same side. A sliding rod 27 is mounted inside the rear side of the frame 2, and the sliding rod 27 is slidably connected to the sliding slider 26 on the same side. A drive chamber 4 is mounted on the top right side of the frame 2. A moving block 5 is slidably mounted on the drive chamber 4. The drive chamber 4 is connected to the moving block 5 via a moving assembly 6. The moving assembly 6 includes a rotating shaft 601, a gear 602, and a rack 603. The rotating shaft 601 is rotatably mounted inside the moving block 5. Moving grooves for the movement of the rotating shaft 601 are provided on the upper and lower side walls of the drive chamber 4. Gear 602 is installed, and racks 603 meshing with gear 602 are installed on both sides of the drive compartment 4. Glue dispensing head 7 is installed on the left side wall of the moving block 5. A pressing assembly 8 is provided on the top left side of the frame 2. The pressing assembly 8 includes a mounting plate 801, a connecting plate 802, a second cylinder 803, and a pressure plate 804. Two sets of mounting plates 801 are provided on the top of the frame 2. The two sets of mounting plates 801 are connected by two sets of connecting plates 802. A second cylinder 803 is provided on the top of each of the two sets of connecting plates 802. The output end of the second cylinder 803 slides through the connecting plate 802 and is connected to the pressure plate 804. Moving rods 25 slide through both sides of the two sets of mounting plates 801. The lower ends of the moving rods 25 are connected to the top of the pressure plate 804. A fixing plate 13 is provided inside the left side of the frame 2.

[0023] At this time, the motor drives the lead screw 24 to rotate, which in turn moves the slider 26. Simultaneously, the slider 26 moves the drive chamber 4 laterally. The slider 26 on the other side of the drive chamber 4 slides above the slide rod 27. Simultaneously, the motor drives the rotating shaft 601 to rotate, which in turn drives the gear 602 to rotate. Since the gear 602 meshes with the rack 603, it causes the moving block 5 to slide above the drive chamber 4. At the same time, the rotating shaft 601 moves inside the moving groove on the surface of the drive chamber 4, causing the glue dispensing head 7 on the surface of the moving block 5 to move back and forth. At this time, the glue dispensing head 7 applies glue to different areas of the cardboard surface. After positioning, the rotating rod 18 drives the rotating plate 19 to rotate again, placing the new cardboard above the glue-coated cardboard. The feeding belt 3 is then fed by the external drive mechanism, moving the cardboard below the pressure plate 804. The pressure plate 804 is then lowered by the second cylinder 803, and the pressure plate 804 moves synchronously with the moving rods 25 on both sides. At this time, the pressure plate 804, together with the fixed plate 13, presses the multi-layer cardboard together, making the cardboard bonded more tightly. The glue dispensing amount of the glue head 7 is calculated in advance to avoid applying too much glue at once, which would cause overflow during the pressing process. The glue dispensing of the glue head 7 is controlled by the electrical control system.

[0024] A storage box 14 is provided on the top front side of the base plate 1. Threaded rods 15 are threadedly connected to the middle of the two side walls of the storage box 14. Push plates 16 are rotatably connected to the front end of the threaded rods 15. Two sets of limiting rods 23 are slidably provided on both sides of the storage box 14. The front ends of the limiting rods 23 are respectively connected to the side wall of the push plate 16 on the same side. The push plate 16 is L-shaped. The bottom of the push plate 16 is slidably connected to the inside of the storage box 14. A fixed column 17 is provided on the top of the base plate 1. A rotating rod 18 is rotatably provided on the top of the fixed column 17. A rotating plate 19 is provided on the top of the rotating rod 18. Mounting frames 20 are provided at both ends of the rotating plate 19. Multiple suction cups 21 are provided at the bottom of the mounting frames 20. A first cylinder 22 is provided at the top of both ends of the rotating plate 19. The output end of the first cylinder 22 is connected to the center of the top of the mounting frame 20.

[0025] In use, after placing the corrugated cardboard inside the storage box 14 on one side of the base plate 1, rotate the threaded rods 15 on both sides of the storage box 14. The threaded rods 15 drive the push plate 16 in front to move. At the same time, the push plate 16 drives the limit rod 23 to slide synchronously. At this time, after the bottom of the push plate 16 slides inside the storage box 14, the corrugated cardboard inside is aligned by the push plates 16 on both sides. Then, the first cylinder 22 drives the mounting frame 20 to descend, so that the multiple suction cups 21 at the bottom of the mounting frame 20 descend and contact the cardboard surface. After the suction cups 21 are adsorbed by the external drive mechanism, the cardboard is taken out. Then, the motor inside the fixed column 17 drives the rotating rod 18 to rotate. At the same time, the rotating rod 18 drives the rotating plate 19 at the top to rotate 180 degrees, and then rotates the cardboard to the top of the feeding belt 3. At the same time, the mounting frame 20 that has not adsorbed the cardboard moves to the top of the storage box 14. At this time, the first cylinder 22 drives the mounting frame 20 to descend again and places the cardboard on the top of the feeding belt 3.

[0026] Working principle: When using the automatic corrugated cardboard gluing machine, after placing the corrugated cardboard into the storage bin 14 on one side of the base plate 1, rotate the threaded rods 15 on both sides of the storage bin 14. The threaded rods 15 drive the front push plate 16 to move, and at the same time, the push plate 16 drives the limit rod 23 to slide synchronously. At this time, after the bottom of the push plate 16 slides inside the storage bin 14, the corrugated cardboard inside is aligned by the push plates 16 on both sides. Then, the first cylinder 22 drives the mounting frame 20 to descend, so that the multiple suction cups 21 at the bottom of the mounting frame 20 descend and come into contact with the cardboard surface. 1. After the cardboard is removed by the external drive mechanism, the motor inside the fixed column 17 drives the rotating rod 18 to rotate. At the same time, the rotating rod 18 drives the top rotating plate 19 to rotate 180 degrees, rotating the cardboard above the feeding belt 3. Simultaneously, the mounting frame 20 with unadsorbed cardboard moves above the storage box 14. At this time, the first cylinder 22 drives the mounting frame 20 to descend again, placing the cardboard on the top of the feeding belt 3. Then, the motor drives the lead screw 24 to rotate, and the lead screw 24 drives the slider 26 to move. At the same time, the slider 26 drives the drive chamber 4 to move laterally. The other drive chamber 4... The slider 26 on the side slides above the slider 27, and at the same time, the rotating shaft 601 can be rotated by the motor. At this time, the rotating shaft 601 drives the gear 602 to rotate. Since the gear 602 and the rack 603 mesh, the moving block 5 slides above the drive chamber 4. At the same time, the rotating shaft 601 moves inside the moving groove on the surface of the drive chamber 4, causing the glue dispensing head 7 on the surface of the moving block 5 to move back and forth. At this time, after the glue dispensing head 7 applies glue to different positions on the surface of the cardboard, the rotating rod 18 drives the rotating plate 19 to rotate again. After placing the new cardboard on top of the cardboard coated with glue, it is driven by the external drive mechanism. The feeding belt 3 feeds the cardboard and moves it below the pressure plate 804. The second cylinder 803 drives the pressure plate 804 to descend. At the same time, the pressure plate 804 drives the moving rods 25 on both sides to move synchronously. At this time, the pressure plate 804 and the fixed plate 13 press the multi-layer cardboard together, making the cardboard bonded more tightly. The glue dispensing head 7 has calculated the glue amount in advance to avoid applying too much glue at once, which would cause overflow during the pressing process. The glue dispensing head 7 is controlled by the electrical control system to complete a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
